Properly Installing A Check Valve From a Sump Pump
Installing a check valve near your sump pump can help protect your home from flooding caused by an outflow of water. To ensure the best performance, it’s important to follow guidelines for proper check valve placement in regard to distance and elevation from the sump pump.
Measure the Outlet Pipe and Select an Appropriate Check Valve
Start the installation process by measuring the outlet pipe of the sump pump. Measure from the center of the pipes outside bulge, and make sure to select a check valve with an opening that closely matches this measurement. Additionally, it is important to select a check valve with a minimum working pressure rating equal to or greater than that of your sump pump. By doing so, you can guarantee that your check valve will last as long as possible and provide maximum protection from flooding.
Place the Check Valve at the End of the Outlet Pipe
When the check valve is installed, it needs to be at the very end of the outlet pipe, directly after the sump pump. Make sure that its flapper or rubber flap faces inwards so when it closes under pressure (such as from a returning flow of water), the force creates a tight seal and does not cause any leaking around it. Additionally, make sure that you affix the check valve firmly with PVC cement or adhesives.
Connect the Check Valve to the Outlet Pipe with PVC Cement
When connecting the check valve to the sump pumps outlet pipe, you should use PVC cement or any other specified adhesive to make sure that it is securely affixed and can handle pressure without breaking apart. This is especially important since when water moves through the check valve, it will usually generate a bit of pressure that could potentially cause it to break off if it isn’t properly connected.
Install a Union Wherever You Need to Disconnect or Remove Parts of the System
Whenever you need to disconnect or remove parts of the sump pump system, you should first install a union at this point. This will provide an extra measure of safety in case you need to take apart the sump pump during a repair or replacement process. Installing this type of union will also ensure that all connections remain watertight and properly seal off against possible leaks when the sump pump is operational.
Test-Run Your Sump Pump Before Closing Up!
Once the check valve is in place, it is important to double check your work and make sure the system functions are working properly. You can do this by testing the sump pump. Simply use a nearby bucket or faucet to fill up the sump pit area with water. Once water levels reach their peak, open up all valves and switches before activating the sump pump to make sure it works correctly.
